| 摘 要： | 介绍了一种新的四杆函数机构综合方法──傅里叶（Ｆｏｕｒｉｅｒ）系数法．四杆机构的从动件运动规律为原动件转角２π的周期函数，故可以拟合成傅里叶级数．其系数是一系列有规律的数，特别是速度规律更为明显．据此，当给定周期性的目标函数时，将其拟合成傅里叶级数，据其系数可以设计出具有一定精度的机构．

| Abstract: | A method of mechanism synthesis --coefficients of Fourier series is introduced. Periodic function of four--bar linkage mechanism can be fitted with Fourier series,these coefficients having clear rules,especially for velocity. The chief purpose of this paper is to synthesize a four--bar linkage mechanism according to the coefficients for a given function,the synthesized mechanisms can meet the demands of the given error. |
